Answer:

a₁ = 2 and d = 3

Step-by-step explanation:

Consider the sequence given by the values of y, that is

2, 5, 8, 11, 14, 17

The first term in the sequence is a₁ = 2

The common difference is

d = 17 - 14 = 14 - 11 = 11 - 8 = 8 - 5 = 5 - 2 = 3

Thus a₁ = 2 and d = 3

Answer:

Slope: $-\dfrac{1}{2}$

Equation: $y=-\dfrac{1}{2}x+8$

Step-by-step explanation:

The line of the best fit passes through the points (0,8) and (4,6).

If the line passes through the points $(x_1,y_1)$ and $(x_2,y_2)$ then the slope of the line is

$\dfrac{y_2-y_1}{x_2-x_1}$

Hence, the slope of the line of the best fit is

$\dfrac{6-8}{4-0}=\dfrac{-2}{4}=-\dfrac{1}{2}$

The equation of the line is

$y=mx+b,$

where m is the slope and b is y-intercept, so the equation of the line of the best fit is

$y=-\dfrac{1}{2}x+8$
